This includes fixing some mistakes, as well as removing
redundant text that doesn't add new information, either because
it literally repeats what the code already says, or is actually
duplicated.

This saves two queries per local overridden message when filling the
cache
(one from RevisionStore::loadSlotRecords, one from
SqlBlobStore::fetchBlobs)
Remove 'user' join, as nothing is getting user information from this
records. Join against comment and actor also not needed, but there is no
option to avoid the join.

Migrate all callers of Hooks::run() to use the new
HookContainer/HookRunner system.
General principles:
* Use DI if it is already used. We're not changing the way state is
managed in this patch.
* HookContainer is always injected, not HookRunner. HookContainer
is a service, it's a more generic interface, it is the only
thing that provides isRegistered() which is needed in some cases,
and a HookRunner can be efficiently constructed from it
(confirmed by benchmark). Because HookContainer is needed
for object construction, it is also needed by all factories.
* "Ask your friendly local base class". Big hierarchies like
SpecialPage and ApiBase have getHookContainer() and getHookRunner()
methods in the base class, and classes that extend that base class
are not expected to know or care where the base class gets its
HookContainer from.
* ProtectedHookAccessorTrait provides protected getHookContainer() and
getHookRunner() methods, getting them from the global service
container. The point of this is to ease migration to DI by ensuring
that call sites ask their local friendly base class rather than
getting a HookRunner from the service container directly.
* Private $this->hookRunner. In some smaller classes where accessor
methods did not seem warranted, there is a private HookRunner property
which is accessed directly. Very rarely (two cases), there is a
protected property, for consistency with code that conventionally
assumes protected=private, but in cases where the class might actually
be overridden, a protected accessor is preferred over a protected
property.
* The last resort: Hooks::runner(). Mostly for static, file-scope and
global code. In a few cases it was used for objects with broken
construction schemes, out of horror or laziness.

This class was last used in ~2008 as @tstarling was developing the
original wikitext Parser. It has since code-rotted and wouldn't work
as a drop in for the Parser class any more anyway. We'll probably
(re)invent something similar when we eventually switch Message
rendering from the legacy parser to Parsoid, but this existing code
isn't a good starting point for that; we'll need to tackle T236812
(splitting Parser into a base class) first.

Repeating the variable name doesn't do anything. Documentation
generators don't need it. It's more stuff to read that doesn't add new
information. And it can become outdated.
Note there are two types of @var docs. When used inline (and not on a
class property) the variable name is needed.

These call the deprecated Language::getLocalisationCache() method and
thereby indirectly access MediaWikiServices. Callers should be changed
to inject a LocalisationCache and use that directly.
There are only a few callers in code search, so it didn't seem worth
adding convenience methods to LocalisationCache. The one caller that was
already using DI was MessageCache, and I injected LocalisationCache
there.

Before c962b48056, the 'loadedLanguages' array was used to track
which languages were loaded and in the cache, with 'cache' being a
simple array. In that commit, the 'cache' array also started being used
for incomplete datasets, which didn't affect 'loadedLanguages'.
Then in 97e86d934b, the 'loadedLanguages' array was removed in favour
of checking keys on 'cache' directly, and 'cache' was converted to
MapCacheLRU.
This led to problem where partially loaded data was mistaken for being
full datasets (fatal error, T208897). This was fixed in a5c984cc59,
by bringing back the 'loadedLanguages' array, which fixed the issue from
the POV of partially loaded data.
However, this then exposed a new problem. The 'cache' data can be evicted
by MapCacheLRU, whereas 'loadedLanguages' is not aware of that. Thus it
claims languages are loaded that sometimes aren't. (This only affects web
requests where more than 5 language codes are involved, per MapCacheLRU.)
Fix this by re-removing the 'loadedLanguages' array, this time
strengthening the 'cache' key check to not just check that the root key
exists, but that it is in fact holding the full dataset as generated by
MessageCache::load(). The 'VERSION' key appears to be a good proxy for
that.

This variable has never been set to anything other than the default value of
24 hours as introduced in 2003 (r2203, r2204; or 036ff960ce, edf6b38626).
The variable has never changed in core, it's not overridden at WMF,
and MessageCache is not constructed anywhere other than ServiceWiring.php
anywhere in repos on Wikimedia Gerrit, indexed by MediaWiki Codesearch,
or any GitHub-hosted repository (incl Wikia repos and WikiHow mirrors).
I've also checked all GitHub-hosted repos for boilerplates and/or public
settings files from devs or prod, and couldn't find any example of
this being overridden (after filtering out copies of the core files
themselves). Rather than having to support potentially hard-to-predict
interactions betweeen caching layers by checking its state, make it
a constant so we can code reason about it more easily.

For some unknown reason, when the `actor` table has few enough NS8 rows
compared to `page` MariaDB 10.1.37 decides it makes more sense to fetch
everything from `actor` then join `revision` then `page` rather than
fetching the rows from `page` in the first place.
We can work around it by telling it to not reorder the query, but then
we also have to reorder it ourselves to put `page` first instead of
`revision`.

This was removed in 97e86d934b in 2018 in favour of using
`$this->cache->has($code)`. This is a problem because there
are cases where only a narrow subset of that structure is
populated (by MessageCache->replace) without things like
$this->overridable (or anything else that MessageCache->load does)
having ocurred yet.
The assumption that keys are only added to $this->cache by
MessageCache->load (or after that method has been called) was
actually true at some point. But, this changed in 2017 when
commit c962b48056 optimised MessageCache->replace to not call
MessageCache->load.

The way isMainCacheable() was used, it always returned false in
non-content languages, because it would try to find strings like
'hidetoc/fr' in the array of message keys (which contains strings like
'hidetoc').
The consequence of this was that MessageCache would check the database
for a MediaWiki:hidetoc/fr page even if it already knew that that page
didn't exist. This is a substantial performance hit when requesting lots
of messages, like when building version hashes for ResourceLoader's
startup module.

Prior to I462554b30, MessageCache::replace() did just that: it took the
existing cache and updated the one entry.
In I462554b30, the rearrangement of work into a DeferredUpdate
introduced a bug: the in-process cache was updated, but when the shared
cache was loaded later the entry was never updated in there so the
shared caches kept the old value. This was found in code review and
worked around by reloading all the messages from the database instead of
updating the existing cache.
But all that extra work reloading everything from the database causes
major slowness saving any MediaWiki-namespace page when the wiki has
many such small pages. Let's go back and fix the bug so replace() can
again replace instead of reloading everything.
